A bill to amend the Solid Waste Disposal Act to modify the requirements respecting liability insurance for underground storage tanks, and for other purposes.

Amends the Solid Waste Disposal Act to extend to November 8, 1989, the effective date for maintaining evidence of financial responsibility for owners and operators of underground storage tanks. Prohibits the first suspension of such financial responsibility requirement for a class or category of tanks from exceeding 360 days. (Such suspension is currently authorized for up to 180 days if the Administrator of the Environmental Protection Agency makes certain determinations.)

Requires the Administrator to assist States in establishing: (1) State assurance funds to enable underground storage tank owners and operators to meet the financial requirements of the Act; and (2) programs to encourage private insurance providers to offer insurance coverage to such owners and operators.
